Fragile X syndrome is the most common cause of intellectual disability in males, affecting approximately 1 in 4,000 males. It is caused by a mutation on the X chromosome, and males only have one X chromosome, making them more susceptible to the condition. Cystic fibrosis and hemophilia are both genetic conditions, but they do not typically cause intellectual disability. Down syndrome is a genetic condition that can cause intellectual disability, but it is equally common in males and females.
